A bottle automatic screen printing machine

Abstract

The invention discloses a bottle body automatic screen printing machine. The machine comprises a conveying and loading device, a circular conveying working line and an unloading device; a bottle bodycircular conveying working line comprises the circular conveying working line arranged on a stand; the circular conveying working line comprises an annular guide rail set, a linear motor magnetic suspension motion mechanism and a servo control system; the linear motor magnetic suspension motion mechanism is provided with a mover for circularly moving along annular guide rails; the mover is provided with a bottle body fixture; a screen plate and an ink curing device are arranged beside the linear motor magnetic suspension motion mechanism; a scraper is arranged on the screen plate; the screen plate and the ink curing device are both positioned above a motion trajectory of the bottle body fixture; and the ink curing device is positioned between an ink plate and the unloading device. The machine is precise in repeated positioning, safe, reliable and high in speed, improves the chromatography precision and the printing quality, adopts ultraviolet rays or electronic beams to cur ink on bottle bodies, and is suitable for printing of some glass bottles and cosmetic bottles with complicated shapes.

Description

Technical field [0001] The invention belongs to the technical field of screen printing and relates to an automatic screen printing machine for bottle bodies. Background technique [0002] As we all know, the existing screen printing machine needs to carry out the multi-color printing through a mechanical transmission mechanism, step by step to move the bottle (or other substrate) from the previous station to the next station, because the conveying process has to be clamped many times. And when the substrate is loosened, transmission errors often occur, especially when printing glass bottles. Because glass bottles are hard and fragile, and the edges of the fragments are extremely sharp, when they fall during transportation, they will be squeezed by the transportation mechanism. If the bottle body is broken or broken, or the fragments are splashed, it will cause serious damage to the machine or personnel. Therefore, the handling speed should not be too fast, the work efficiency is ...

AI Technical Summary

Problems solved by technology

[0002] As we all know, to complete the multi-color printing of the existing screen printing machine, the bottle (or other substrate) needs to be transported step by step from the previous station to the next station through a mechanical transmission mechanism. And loose the substrate, there are often transmission errors, especially when printing glass bottles, because glass bottles are hard and fragile, and the edges of the fragments are extremely sharp, when they fall during the handling process, they are squeezed by the handling mechanism or collision, causing the bottle body to be damaged and cracked, and the fragments splashed, it will cause serious injury to the machine or personnel, so the handling speed should not be too fast, the work efficiency is relatively low and the failure rate is high; because of the large number of clamping, dozens of The bottle clamping mechanism clamps the bottle at the same time according to the rhythm, which produces a lot of noise; in addition, the existing screen printing machine uses a 3 kW to 5 kW high-pressure mercury lamp to cure the ink, which consumes a lot of energy and does not meet the current environmental protection concept of energy saving and emission reduction.
